November 18, 2025 — NTT, Inc. will host its annual R&D Forum in Tokyo on November 19-21 and November 25-26 to showcase its latest technological advancements.
This year’s forum, themed “IOWN: Quantum Leap,” aligns with the United Nations’ designation of 2025 as the “International Year of Quantum Science and Technology” and the Japanese government’s focus on quantum industrialization.
NTT will present breakthroughs from its Innovative Optical and Wireless Network (IOWN) Initiative, designed to create an advanced communications infrastructure using optical photonics technologies. These technologies aim to achieve ultra-high capacity, ultra-low latency, and ultra-low power consumption.
A key highlight is the collaboration between NTT and OptQC, formalized through a new agreement. The companies will work together to develop scalable and reliable optical quantum computers, combining NTT’s optical communications expertise with OptQC’s room-temperature optical quantum computer technology. Their goal is to create a 1-million qubit optical quantum computer by 2030. The technology will apply optical communications technologies developed by NTT under the IOWN Initiative with OptQC’s world-first optical quantum computer that operates at room temperature and pressure.
The NTT R&D Forum will also feature several exhibits demonstrating NTT’s leadership in AI innovation. These include technologies that are currently transforming enterprise workflows and research advancements that will shape the future of AI capabilities. A key feature is NTT’s new “Large Action Model” (LAM) to advance personalized marketing.
NTT’s next-generation LLM “tsuzumi 2” is now available and is a lightweight model that overcomes the electricity consumption, rising operating costs, and security risks of competitor LLMs. In business-case deployments, tsuzumi 2 is proven to deliver performance on par with or exceeding that of larger models while offering a superior cost-performance ratio.
NTT DOCOMO have developed a new AI technology called the Large Action Model (LAM) to enable highly personalized, one-to-one marketing strategies. The LAM develops custom marketing tailored to the individual by pre-learning patterns in behavioral sequences from customer time-series data to predict customers’ intent and then further learning the content, method, timing and effectiveness of promotional measures to personalize them.
NTT Research, the Silicon Valley-based fundamental research arm of NTT, will announce a new set of cybersecurity solutions powered by attribute-based encryption (ABE) to combat the rising threat of quantum computing and AI. ABE, which enables fine-grain access control and enforcement policies, was first proposed by NTT Research Cryptography & Information Security Lab Director Dr. Brent Waters and his co-author, Dr. Amit Sahai, in a 2005 paper, “Fuzzy Identity-based Encryption.”
NTT Mobility, a new venture capitalizing on NTT’s networking expertise, will drive level 4 autonomous vehicle adoption across Japan. NTT aims to offer autonomous driving services throughout Japan by fiscal year 2027, with three primary business activities: autonomous driving vehicle provision and management services; autonomous driving implementation and operation support services; remote monitoring system provision services.
NTT will also showcase a parametric object-recognition-radio-estimation model, a new technology automatically estimates whether remote monitoring video and vehicle-related information transmitted from autonomous vehicles to the control room are of sufficient quality to reliably detect objects suddenly appearing in front of the vehicle.
